Abstract

The valve has a housing (6) with valve seats (4, 5) rotatably supported at a drive shaft (1). The drive shaft is guided between flaps (2, 3) through a part of the housing, where longitudinal axes of the flaps are not parallel to each other. An intersection angle between the longitudinal axes of the flaps lies in a range of 120 and 150 degrees. The flaps are designed in round and disc shape and include grooves at its outer edges, where the grooves are adapted for accommodating a tolerance rings.

Description

Die Erfindung bezieht sich auf ein Ventil sowie auf eine Verwendung des Ventils. Ventile, beispielsweise für Gaskanäle, sind bekannt. In der DE 102 51 385 A1 wird ein Ventil beschrieben, das aus einem Gehäuse mit einem Ventilsitz für eine Klappe, die an einer Antriebswelle drehbar gelagert ist, besteht, bei dem außen um die Klappe ein doppelt gewundener Lamellenring in einer umlaufenden Nut der Klappe angeordnet ist. Ist es beispielsweise erwünscht, größere Durchsätze durch das Ventil zu führen, so hat es sich konstruktiv bewährt, zusätzlich zu der Klappe eine weitere Klappe anzuordnen, um so den Durchfluss höherer Durchsätze zu erzielen. Da beide Klappen in der Regel an ein und derselben Antriebswelle drehbar gelagert sind, ist jedoch in vielen Fällen auf Grund der Druckunterschiede zwischen der Druck- und der Saugseite des Ventils eine relativ aufwendige Lagerung der Antriebswelle erforderlich, so dass nachteilige Leckluftströmungen an der Antriebswelle vermieden werden können.The invention relates to a valve and to a use of the valve. Valves, for example for gas channels, are known. In the DE 102 51 385 A1 a valve is described, which consists of a housing with a valve seat for a flap which is rotatably mounted on a drive shaft, in which the outside of the flap a double wound lamellar ring is arranged in a circumferential groove of the flap. For example, if it is desired to pass greater throughputs through the valve, then it has been found to be constructive to place another flap in addition to the flap so as to achieve the flow of higher throughputs. Since both valves are usually rotatably mounted on one and the same drive shaft, however, in many cases, due to the pressure differences between the pressure and the suction side of the valve, a relatively complex storage of the drive shaft is required, so that adverse leakage air flows are avoided on the drive shaft can.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Ventil zu schaffen, bei dem auf die konstruktiv aufwendige Ausgestaltung der Lager für die Antriebswelle verzichtet werden kann und bei dem es nicht zu den nachteiligen Leckluftströmen kommt. Der Erfindung liegt ferner die Aufgabe zugrunde, eine spezielle Verwendung des Ventils zu schaffen.Of the Invention is therefore an object of the invention to provide a valve, in which on the structurally complex design of the bearings for the drive shaft can be waived and in which it is not the detrimental Leakage air currents comes. The invention is also based on the object, a special Use of the valve to create.

Die der Erfindung zugrunde liegende Aufgabe wird durch ein Ventil gelöst, das aus einem Gehäuse mit einem ersten Ventilsitz für eine erste Klappe und einem zweiten Ventilsitz für eine zweite Klappe, die an einer Antriebswelle drehbar gelagert sind, besteht, bei dem die Antriebswelle zwischen der ersten Klappe und der zweiten Klappe durch ein Teil des Gehäuses geführt wird und bei dem die Längsachse der ersten Klappe und die Längsachse der zweiten Klappe nicht parallel zueinander verlaufen. Der Ventilsitz kann beispielsweise auch Teil des Gehäuses sein. Die erste Klappe und die zweite Klappe sind rund und scheibenförmig ausgebildet und weisen an ihren Außenkanten beispielsweise Nuten auf, die für die Aufnahme von Toleranzringen geeignet sind. Es hat sich in überraschender Weise gezeigt, dass durch die vorteilhafte Anordnung der ersten Klappe und der zweiten Klappe unter der Realisierung eines Schnittwinkels der beiden Längsachsen auf aufwendige konstruktive Ausgestaltungen der Lager für die Antriebswelle verzichtet werden kann, was dadurch erzielt wird, dass die jeweiligen Lager hinsichtlich ihrer Umgebung eindeutig einem einzigen Druck, entweder auf der Druckseite oder auf der Saugseite, zugeordnet werden können. Die nachteilige Ausbildung von Leckluftströmungen wird somit auf eine einfache Weise verhindert. Ferner werden axiale Kraftkomponenten durch die Anordnung der ersten Klappe und der zweiten Klappe vorteilhaft kompensiert.The The object underlying the invention is achieved by a valve, the from a housing with a first valve seat for a first flap and a second valve seat for a second flap which on a drive shaft are rotatably mounted, in which the Drive shaft between the first flap and the second flap through a part of the housing guided is and in which the longitudinal axis of first flap and the longitudinal axis the second flap does not run parallel to each other. The valve seat may for example also be part of the housing. The first flap and the second flap are round and disc-shaped and have on the outside edges For example, grooves on, for the Inclusion of tolerance rings are suitable. It has become more surprising Ways shown that by the advantageous arrangement of the first Flap and the second flap under the realization of a cutting angle the two longitudinal axes to elaborate structural configurations of the bearing for the drive shaft can be dispensed with, which is achieved by the respective Bearings in terms of their environment clearly a single pressure, either on the pressure side or on the suction side can. The disadvantageous formation of leakage air flows is thus on a easy way prevented. Furthermore, axial force components advantageous by the arrangement of the first flap and the second flap compensated.

Eine bevorzugte Ausgestaltung der Erfindung besteht darin, dass der Schnittwinkel α zwischen der Längsachse der ersten Klappe und der Längsachse der zweiten Klappe im Bereich von 120° und 150° liegt. Auf Grund der konstruktiven Ausgestaltung der meisten Gehäuse der Ventile ist in einem solchen Winkelbereich der Einsatz des Ventils für vielerlei Einsatzzwecke gewährleistet.A preferred embodiment of the invention is that the intersection angle α between the longitudinal axis the first flap and the longitudinal axis the second flap is in the range of 120 ° and 150 °. Due to the constructive Design of most cases the valves are in such an angular range of use of the valve for many things Intended purposes.

Gegenstand der Erfindung ist schließlich die Verwendung des Ventils als Gasrückführventil eines Kraftfahrzeuges. Gase, die durch ein Gasrückführventil eines Kraftfahrzeuges geleitet werden, weisen in der Regel hohe Temperaturen und große Temperaturschwankungen auf, wobei die Druckunterschiede zwischen der Druck- und der Saugseite relativ groß sind. Eine Bildung von Leckluft ist in diesem Falle völlig unerwünscht. Eine Verwendung des erfindungsgemäßen Ventils als Gasrückführventil eines Kraftfahrzeuges ist daher besonders vorteilhaft.object The invention is finally the use of the valve as a gas recirculation valve of a motor vehicle. Gases passing through a gas recirculation valve a motor vehicle are directed, usually high Temperatures and big ones Temperature fluctuations, with the pressure differences between the pressure and the suction side are relatively large. A formation of air leakage is completely in this case undesirable. A use of the valve according to the invention as a gas recirculation valve a motor vehicle is therefore particularly advantageous.

Die Erfindung wird nachfolgend anhand der Zeichnung (1 bis 3) näher und beispielhaft erläutert.The invention will be described below with reference to the drawing (in which 1 to 3 ) explained in greater detail and by way of example.

2 zeigt die Anordnung der ersten Klappe und der zweiten Klappe an der Antriebswelle in vereinfachter Form im Querschnitt. 2 shows the arrangement of the first flap and the second flap on the drive shaft in a simplified form in cross section.

3 zeigt die Anordnung einer ersten Klappe und einer zweiten Klappe an einer Antriebswelle nach dem Stand der Technik. 3 shows the arrangement of a first flap and a second flap on a drive shaft according to the prior art.

In 1 ist das Ventil im Querschnitt dargestellt. Das Ventil besteht aus einem Gehäuse 6 mit einem ersten Ventilsitz 4 für eine erste Klappe 2 und einem zweiten Ventilsitz 5 für eine zweite Klappe 3, die an einer Antriebswelle 1 drehbar gelagert sind. Bei dem Ventil wird die Antriebswelle 1 zwischen der ersten Klappe 2 und der zweiten Klappe 3 durch ein Teil des Gehäuses 6 geführt, wobei die Längsachse der ersten Klappe 2 und die Längsachse der zweiten Klappe 3 nicht parallel zueinander verlaufen, sondern einen gemeinsamen Schnittwinkel α, der beispielsweise für viele Einsatzzwecke im Bereich von 120° bis 150° liegt, aufweisen. Das Ventil dient hierbei in vorteilhafter Weise als Gasrückführventil eines Kraftfahrzeuges.In 1 the valve is shown in cross-section. The valve consists of a housing 6 with a first valve seat 4 for a first flap 2 and a second valve seat 5 for a second flap 3 attached to a drive shaft 1 are rotatably mounted. The valve becomes the drive shaft 1 between the first flap 2 and the second flap 3 through a part of the housing 6 guided, with the longitudinal axis of the first flap 2 and the longitudinal axis of the second flap 3 not parallel to each other, but a common cutting angle α, which is for example for many purposes in the range of 120 ° to 150 °. The valve serves advantageously as a gas recirculation valve of a motor vehicle.

In 2 ist die Anordnung der ersten Klappe 2 und der zweiten Klappe 3 an der gemeinsamen Antriebswelle 1 vereinfacht und schematisch dargestellt. Die Längsachse der ersten Klappe 2 und die Längsachse der zweiten Klappe 3 verlaufen nicht parallel zueinander, sondern weisen einen gemeinsamen Schnittwinkel α auf.In 2 is the arrangement of the first flap 2 and the second flap 3 at the joint arrival drive shaft 1 simplified and shown schematically. The longitudinal axis of the first flap 2 and the longitudinal axis of the second flap 3 do not run parallel to each other, but have a common cutting angle α.

In 3 ist die Anordnung einer ersten Klappe 2* und einer zweiten Klappe 3* an einer gemeinsamen Antriebswelle 1* vereinfacht und schematisch nach dem Stand der Technik dargestellt. Zwischen der ersten Klappe 2* und der zweiten Klappe 3* wird die Antriebswelle 1* durch einen Teil des Gehäuses 6* geführt und wird durch die Lagerung 6a* gelagert. Durch diese nachteilige Anordnung der ersten Klappe 2* und der zweiten Klappe 3*, deren Längsachsen im Gegensatz zur Erfindung parallel verlaufen, ergibt sich in nachteiliger Weise, dass an dem einen Ende des Lagers 6a* der Druck P1 und an dem anderen Ende des Lagers 6a* der Druck P2 anliegt. Sofern es sich bei dem Druck P1 um den Druck handelt, der an der Druckseite des Ventils anliegt, ergibt sich, dass der Druck P1 größer ist als der Druck P2. Die Folge davon ist eine Leckströmung im Lager 6a*, die ausgehend von der Seite des Druckes P1 hin zur Seite des Druckes P2 in Pfeilrichtung verläuft. Um diese Leckströmung zu unterbinden, ist es erforderlich, das Lager 6a* konstruktiv relativ aufwendig auszugestalten, was in der Regel nicht erwünscht ist. Die damit verbundenen Nachteile werden durch das erfindungsgemäße Ventil vermieden.In 3 is the arrangement of a first flap 2 * and a second flap 3 * on a common drive shaft 1* simplified and shown schematically according to the prior art. Between the first flap 2 * and the second flap 3 * becomes the drive shaft 1* through a part of the housing 6 * guided and is by the storage 6a * stored. By this disadvantageous arrangement of the first flap 2 * and the second flap 3 * whose longitudinal axes, in contrast to the invention are parallel, results in a disadvantageous manner that at one end of the bearing 6a * the pressure P1 and at the other end of the camp 6a * the pressure P2 is applied. If the pressure P1 is the pressure which prevails on the pressure side of the valve, it follows that the pressure P1 is greater than the pressure P2. The consequence of this is leakage in the bearing 6a * , which extends from the side of the pressure P1 toward the side of the pressure P2 in the arrow direction. To prevent this leakage, it is necessary to the bearing 6a * structurally relatively complex to design, which is not desirable in the rule. The associated disadvantages are avoided by the valve according to the invention.
